Rotary switch for attenuator

Alex M · 30th September 2011, 01:21 PM

I am looking for a couple of 24-position rotary switches to build up attenuators for my DIY RTP3, replacing Sfernice P11 pots. I have collected a complete set of resistors, and just now need to get the switches.

Allen Wright recommended ELMA switches, but these are very expensive (for instance, HiFi Collective charge £108 for a 4-pole switch).

First of all, is there a less pricey (preferably European) source for ELMA parts?

Secondly, how much would I lose out in terms of longevity and quality if I settled for cheaper switches?

Thanks!

Partsconnexion has Connecx switches for $20 US, but they are in Canada.

Get the ELMA. They're expensive but they last forever.
